On long wire antennas with multiple excitations and loadings

Matrix methods are applied for analysis and design of long thin-wire antennas with multiple excitations. It is shown how feed voltages can be determined to provide either specified values in a given pattern or maximum gain in some specified direction. Also, it is shown how passive loading can be included in the computational procedures and how in some simple cases load values can be computed to maximize gain in a given direction with respect to an unloaded wire of the same dimensions.
